论文摘要
在经典近似中，相对论电子在外部场中发出的辐射的两个特性详细介绍：1）光谱总和规则及其与原子理中振荡器强度的总和规则的关系。过滤的总和规则可用于删除红外线或紫外线差异。 2）“半裸电子”效应，例如Landau-Pomeranchuk-Migdal和Ternovskij-Shul'ga-Fomin效果。当引入明显的横向速度时，最好理解这些特性。
Two properties of the radiation emitted by a relativistic electron in an external field, in the classical approximation, are presented in details: 1) spectral sum rules and their relationship with the sum rules for oscillator strength in atomic physics. Filtered sum rules can be used to remove infrared or ultraviolet divergences. 2) "half-naked electron" effects like the Landau- Pomeranchuk-Migdal and Ternovskij-Shul'ga-Fomin effects. These properties are best understood when introducing the apparent transverse velocity.
